Neurokinin A is a ten amino acid putative transmitter synthesized in the neurons it is present in. Neurokinin A is a member of the family called Tachykinins which also include Neurokinin B, Substance P, Physalaemin, and Eledoisin. Neurokinin A shares 6 of 10 peptide homologies with Neurokinin B even though they are produced by different genes. Neurokinin A is also very similar in structure to Substance P and produces some of the same biological actions as Substance P. Neurokinin A is a potent bronchoconstrictor. In the gut, Neurokinin A is produced by the intrinsic enteric nervous system.
